run train.py error

[june1819]

Dear Dr.Mentzer
I can't run "python train.py -h", but "python test.py -h" works well.
"python train.py -h" error: ValueError: unsupported format character 'O' (0x4f) at index 38. File "train.py", line 125, in
main(sys.argv[1:]) File "train.py", line 91, in main flags = p.parse_args(args)

I can't run "python train.py configs/ms/cr.cf configs/dl/oi.cf log_dir -p upsampling=deconv" to train dataset. but I can run it with "python train.py configs/ms/cr.cf configs/dl/oi.cf log_dir"
Please answer my question
thank you

Hi did you resolve this? It sounds like something goes wrong with encoding?

Dear Dr.Mentzer
first question：“python train.py -h” report error in "/lib/python3.7/argparse.py". I think my python version(3.7.8) is error. What your python concrete version is？（3.7.1 ，3.7.2 or others？）
second question：what "-p upsampling=deconv" means? The train command with "-p upsampling=deconv" reported error "ValueError: Unused params:

• upsampling"

Can you print the complete stack trace of the -h command? Also, what's your operating system and shell?
And you should be able to train without the -p flag, that was just to illustrate the config parsing.

operating system：Ubuntu. shell: /bin/bash
I can run train command without -p. thanks for explanation

[fab-jul]

Hey, thanks for the stack trace. Turns out there was a % in a help message causes this exception. Fixed in latest commit (4ca100e).

Regarding the -p upsampling=deconv, I cannot reproduce your error message. But I updated the readme to make it a bit more clear that this is not the default command (9133bed)

Thanks for the feedback. Let me know if you find anything else!
